[0018] A method for an aviation filter aluminum shell riveting device, the method includes the following steps:

[0019] S1: Placement of the sealing ring fixing plate:

[0020] The sealing ring fixing plates used in the aviation filter aluminum shell are sequentially placed on the upper parts of multiple central platforms. Before placing the sealing ring fixing plates, according to the sizes of different specifications of the sealing ring fixing plates, the electric slider is turned on to make the lower ring rotate. The rotation of the lower ring makes the sliding plate slide through the moving groove, and finally the circular holes on multiple adjusting parts are in one-to-one correspondence with the multiple circular holes on the sealing ring fixing plate to meet the alignment of the circular holes on the sealing ring fixing plates with different diameters.

[0021] S2: Conveying of the sealing ring fixing plate and pushing of the threaded cover plate:

[0022] Before sequentially conveying the sealing ring fixing plates, the first motor is turned on to make multiple drive shafts rotate. The rotation of the drive shafts drives the support plates to sequentially perform a cyclic operation of lifting-forward-downward through the telescopic plates, so as to convey the placed sealing ring fixing plates under the lowering unit. Subsequently, the electric push plate is turned on to push the threaded cover plate for riveting with the sealing ring fixing plate, and push it above the sealing ring fixing plate.

[0023] S3: Riveting operation:

[0024] After the threaded cover plate is pushed and fitted with multiple sealing ring fixing plates, the second push rod is opened according to the distance between the multiple sealing ring fixing plates. The opening of the second push rod enables the corresponding positioning between the multiple positioning plates and the sealing ring fixing plates. Subsequently, the electric slider is opened to make the riveting machine slide in the positioning groove until it is coaxial with the round holes on one side of the sealing ring fixing plate. Then, the second motor is turned on to drive the driving block to drive the multiple through grooves to rotate in sequence, so that the riveting machine sequentially performs riveting operations between the round holes on the sealing ring fixing plate and the threaded cover plate.

[0025] Advantages of the present invention:

[0026] 1. When the moving plate moves downward in the present invention, it drives the lifting cylinder to move downward. At this time, the inclined block slides downward along the top of the middle component until the middle component and the sliding part are engaged, thereby clamping the middle component. As the moving plate moves forward, it drives multiple sealing ring fixing plates to be conveyed forward at equal intervals. As the moving plate is lifted upward, it drives the lifting cylinder to rise. The inclined blocks on both sides of the lifting cylinder disengage from lifting the middle component. At this time, the clamping parts on both sides rise above the conveying rack. By repeatedly moving upward-forward-downward of the moving plate, multiple sealing ring fixing plates are conveyed at equal intervals, so as to place the threaded cover plates above them in sequence.

[0027] 2. In the present invention, when the electric slider is turned on to drive the lower ring to rotate, the circular block moves through the moving groove when the lower ring rotates. When the circular block moves, the sliding plate slides in the vertical block, so that the adjusting part slides in the adjusting groove. Finally, the riveting holes in the middle of the upper surfaces of multiple adjusting parts correspond one by one to the holes circumferentially opened on the sealing ring fixing plates of different specifications, so as to meet the riveting of the round holes on the sealing ring fixing plates of different diameters.

[0028] 3. When the round holes on the placed sealing ring fixing plates and the threaded cover plates are sequentially riveted in the present invention, the riveting unit performs riveting operations on them. Then, the second motor is turned on to drive the driving plate to rotate. The rotation of the driving plate contacts the multiple through grooves through the driving block in sequence, so that the round holes on the sealing ring fixing plates corresponding to the upper sides of the multiple through grooves are sequentially rotated below the riveting unit, so that the riveting unit can perform riveting operations on them.

[0029] 4. In the present invention, by rotating the threaded rod, the upper side plate moves downward to contact the lower side plate, and then the electric push plate is opened to extend and retract to push the threaded cover plate. By cooperating the electric push plate with multiple conveyed sealing ring fixing plates, the threaded cover plates are continuously placed on the surfaces of the conveyed sealing ring fixing plates.

[0044] An aviation filter aluminum shell riveting device and its method are characterized by manufacturing riveting with aluminum forgings for aerospace use, and the IPC classification number is: B21J*.

[0045] As Figure 1-10 shown, an aviation filter aluminum shell riveting device includes a base 1. A conveyor device 2 is fixedly installed in the middle of the upper end surface of the base 1. The conveyor device 2 includes a conveyor frame 210 connected to the base 1. A set of symmetrically arranged driving shafts 211 are correspondingly installed on both sides of the conveyor frame 210. The driving shafts 211 are rotatably connected to the conveyor frame 210. Belt pulleys 212 are fixedly installed on both of the two driving shafts 211 in a set. A belt 213 is provided between the belt pulleys 212 for transmission. A first motor 214 is fixedly installed on one side of the conveyor frame 210 through a motor plate;

[0046] The output end of the first motor 214 is fixedly connected to the drive shaft 211 on one side. One end of the drive shaft 211 is provided with a telescopic plate 215. A connecting rod 216 is rotatably installed between the left and right corresponding telescopic plates 215. Support plates 217 are fixedly installed on both sides of the connecting rod 216. A moving plate 218 is installed between the two support plates 217. A lowering unit 3 is provided on one side of the conveying frame 210, and a riveting unit 4 is fixedly installed on the other side of the conveying frame 210. When the first motor 214 is turned on, the drive shafts 211 are driven to rotate synchronously through the belt pulleys 212 and the belt 213, thereby driving the telescopic plates 215 connected to the drive shafts 211 to rotate. The rotation of the telescopic plates 215 causes the moving plate 218 above the connecting rod 216 to perform repeated upward-forward-downward movements, thereby driving the multiple seal ring fixing plates above to be conveyed forward at equal intervals. And the telescoping of the telescopic plates 215 facilitates the adjustment of the conveying interval of the seal ring fixing plates during conveying.

[0047] Multiple sets of U-shaped plates 221 are installed on the moving plate 218. A lifting cylinder 222 is fixedly installed between each set of U-shaped plates 221. Side grooves are correspondingly opened on both sides of the lower part of the lifting cylinder 222. Side rods 223 are slidably installed in the side grooves. Inclined blocks 224 are correspondingly installed on the sides of the two side rods 223 close to each other. Springs are sleeved outside the side rods 223.

Rectangular plates 235 are fixedly installed on the sides of the two special-shaped tubes 232 close to each other. Connecting tubes 236 are fixedly installed on the front and rear sides of the rectangular plates 235. A central platform 237 is fixedly installed between the front and rear connecting tubes 236. When the moving plate 218 moves downward, it drives the lifting cylinder 222 to move downward. At this time, the inclined block 224 slides downward along the top of the middle member 233 until the middle member 233 is clamped between the middle member 233 and the sliding member 234. As the moving plate 218 moves forward, it drives multiple seal ring fixing plates to be conveyed forward at equal intervals. As the moving plate 218 rises upward, it drives the lifting cylinder 222 to rise. The inclined blocks 224 on both sides of the lifting cylinder 222 move away from lifting the middle member 233. At this time, the clamping members 231 on both sides rise above the conveying frame 210. Through the repeated upward-forward-downward movement of the moving plate 218, multiple seal ring fixing plates are conveyed at equal intervals, so as to place the threaded covers above them in sequence.

When placing sealing ring fixing plates of different specifications, the electric slider is turned on to drive the lower ring 242 to rotate. When the lower ring 242 rotates, it drives the circular block 246 to move through the moving groove 243. When the circular block 246 moves, it makes the sliding plate 245 slide in the vertical block 244, so that the adjusting member 248 slides in the adjusting groove 247. Finally, the riveting holes in the middle of the upper surfaces of the plurality of adjusting members 248 are in one-to-one correspondence with the holes circumferentially opened on the sealing ring fixing plates of different specifications, so as to meet the riveting of the circular holes on the sealing ring fixing plates of different diameters.

Subsequently, the second motor 254 is turned on to make the driving plate 255 rotate. The driving plate 255 rotates and the driving block 256 contacts with a plurality of through grooves 252 successively, so that the circular holes on the sealing ring fixing plates corresponding to the upper sides of the plurality of through grooves 252 are successively rotated to the lower part of the riveting unit 4, so that the riveting unit 4 can perform riveting operations on them.

[0055] A method for an aviation filter aluminum shell riveting device, the method comprising the following steps:

[0056] S1: Placement of the seal ring fixing plate:

[0057] The seal ring fixing plates used in the aviation filter aluminum shell are sequentially placed on the upper parts of multiple central platforms 237. Before placing the seal ring fixing plates, according to the sizes of different specifications of the seal ring fixing plates, the electric slider is opened to rotate the lower ring 242. The rotation of the lower ring 242 causes the slide plate 245 to slide through the moving groove 243, and finally the round holes on multiple adjusting parts 248 are aligned with the multiple round holes on the seal ring fixing plate one by one to meet the alignment of the round holes on the seal ring fixing plates with different diameters.

[0058] S2: Conveyance of the seal ring fixing plate and pushing of the threaded cover plate:

[0059] Before sequentially conveying the seal ring fixing plates, the first motor 214 is turned on to rotate multiple drive shafts 211. The rotation of the drive shafts 211 drives the support plates 217 to sequentially perform a cyclic operation of lifting-forward-downward through the telescopic plates 215, so as to convey the placed seal ring fixing plates under the lowering unit. Then, the electric push plate 324 is opened to push the threaded cover plate for riveting with the seal ring fixing plate, and push it above the seal ring fixing plate.

[0060] S3: Riveting operation:

[0061] After the threaded cover plate is pushed and fitted with multiple sealing ring fixing plates, the second push rod 48 is opened according to the distance between the multiple sealing ring fixing plates. When the second push rod 48 is opened, the multiple alignment plates 47 are corresponding to the sealing ring fixing plates. Subsequently, the electric slider is opened to make the riveting machine 493 slide in the alignment groove 492 until it is coaxial with the round holes on one side of the sealing ring fixing plate. Then, the second motor 254 is opened to drive the driving block 256 to drive the multiple through grooves 252 to rotate in sequence, so that the riveting machine 493 rivets the round holes on the sealing ring fixing plate and the threaded cover plate in sequence.

[0062] When the present invention is in use, the sealing ring fixing plates used in the aluminum shell of the aviation filter are sequentially placed on the upper parts of multiple central platforms 237. Before the sealing ring fixing plates are placed, according to the sizes of the sealing ring fixing plates with different specifications, the electric slider is opened to drive the lower ring 242 to rotate. When the lower ring 242 rotates, it drives the round block 246 to move through the moving groove 243. When the round block 246 moves, the sliding plate 245 slides in the vertical block 244, so that the adjusting member 248 slides in the adjusting groove 247. Finally, the riveting holes in the middle of the upper surfaces of the multiple adjusting members 248 correspond to the holes circumferentially arranged on the sealing ring fixing plates with different specifications one by one, so as to meet the riveting requirements for the round holes on the sealing ring fixing plates with different diameters.

[0063] The belt pulley 212 and the belt 213 drive the multiple drive shafts 211 to rotate synchronously, and then drive the telescopic plate 215 connected to the drive shaft 211 to rotate. The rotation of the telescopic plate 215 makes the moving plate 218 above the connecting rod 216 perform repeated up - forward - down movements, so as to drive the multiple sealing ring fixing plates above to be conveyed forward at equal intervals. And the telescopic movement of the telescopic plate 215 is convenient for adjusting the conveying distance of the sealing ring fixing plates during conveying. When the moving plate 218 moves downward, it drives the lifting cylinder 222 to move downward. At this time, the inclined plane block 224 slides downward along the top of the middle member 233 until the middle member 233 is between the sliding member 234 to lift the middle member 233. As the moving plate 218 moves forward, it drives the multiple sealing ring fixing plates to be conveyed forward at equal intervals. As the moving plate 218 rises, it drives the lifting cylinder 222 to rise, and the inclined plane blocks 224 on both sides of the lifting cylinder 222 are disengaged from the clamping of the middle member 233. At this time, the clamping members 231 on both sides rise above the conveying frame 210. Through the repeated up - forward - down movements of the moving plate 218, the multiple sealing ring fixing plates are conveyed at equal intervals, so as to place the threaded cover plates above them in sequence.

[0064] When successively riveting the round holes on the placed sealing ring fixing plate and the threaded cover plate, the riveting unit 4 performs riveting operations on them. Subsequently, the second motor 254 is turned on to rotate the driving plate 255. The rotation of the driving plate 255 successively contacts a plurality of through grooves 252 through the driving block 256, so that the round holes on the sealing ring fixing plate corresponding to the upper sides of the plurality of through grooves 252 are successively rotated below the riveting unit 4, so that the riveting unit 4 can perform riveting operations on them. When pushing the threaded cover plate onto the successively conveyed sealing ring fixing plates, rotate the threaded rod 318 to move the upper side plate 319 downward to contact the lower side plate 316, and then turn on the telescopic electric push plate 324 to push the threaded cover plate. By cooperating the electric push plate 324 with a plurality of conveyed sealing ring fixing plates, the threaded cover plates are continuously placed on the surfaces of the conveyed sealing ring fixing plates;

[0065] When riveting a plurality of sealing ring fixing plates covered with threaded cover plates, turn on the second push rod 48 to drive the connecting plate 49 to drive the alignment plate 47 in the middle to slide. At this time, under the action of the contraction frame 490, the distance between the plurality of alignment plates 47 is adjusted. Subsequently, the riveting machine 493 is adjusted to be concentric with the round hole on the sealing ring fixing plate. Then turn on the first push rod 44 to move the front side plate 45 downward to contact the riveting machine 493 at the riveting hole. Then the riveting machine 493 can be turned on to rivet the sealing ring fixing plate and the threaded cover plate.

Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention.
